So “Mary” (let’s pretend it really is her) is now omniscient like God, when not even Satan has that power?
By what power does a dead human have ability to hear my thoughts and meditations?
When we die, only our body dies and turns to dust. Our soul meets Christ at the Particular Judgment at the moment of our death. Our soul is alive.
Christ will judge “Depart from me. I never knew you.” or “Come with me”.....either to Purgatory or straight to heaven.
Then, remember that everyone will see your judgment at the General Judgment at the end of time when the sheep are separated from the goats.
